Abstract

Introduction: One of the phenomena that decrease the quality of surface water is the emergence of EUTROPHICATION which is created as a result of the introduction of high nutrients such as nitrate and phosphorus into the water. In higher reservoirs such as Ekbatan dam, the potential of occurring such a phenomenon increases very much and algae grow in it extensively. The aim of this study was to investigate the EUTROPHICATION of Ekbatan dam based on the Carlsonand Chapra indexes.Materials & Methods: Inthis study, EUTROPHICATION of the Akbatan Lake was determined by monthly measurements of nitrate, phosphate and chlorophyll during 2010. The samplings were conducted in the depth of 0.5m in seven spots in the lake. It was measured by standard methods and then Carlson EUTROPHICATION index was determined using mathematical relations.Findings: Results showed that the most EUTROPHICATION status was for August (53.66 Eutrophic) and the least EUTROPHICATIONstatus was for February (45.97 Eutrophic). This shows that the reservoir’ssotrophic conditions have improved in the winter. The highest EUTROPHICATION status was observed at Station No.6of the Lakes.Conclusion: With regard to considering the Carlson index and N/P ratio, phosphoru scompound was the main factor for EUTROPHICATION that had entered the lake reservoir from external resources. The EUTROPHICATION indexes showed that the lake has dangerous EUTROPHICATION conditions in most months of the year; this phenomenon can be serious in dry years and reduce dissolved oxygen in the water and consequently reduce the quality of the water entering the dam.
